Hand Driven Generator Type Insulation Testers

Hand Driven Generator Type Insulation Testers

Product Category :    Insulation Testers

Supplier                :    Yokins Instruments

Key Features of Hand Driven Generator Type Insulation Testers

  • Cross coil indicator: the indicating movement is of the cross coil ratio type and is designed so that voltage fluctuation caused by irregular cranking have no influence on the results of measurement.
  • Infinity adjustment: this has been provided in the instrument.
  • Silent generator: the ac magnet hand generator drive is extremely smooth and silent. There are no carbon brushes and commutators, to be replaced as in dc generators.

Key Features of Hand Driven Generator Type Insulation Testers
  • Cross coil indicator: the indicating movement is of the cross coil ratio type and is designed so that voltage fluctuation caused by irregular cranking have no influence on the results of measurement.
  • Infinity adjustment: this has been provided in the instrument.
  • Silent generator: the ac magnet hand generator drive is extremely smooth and silent. There are no carbon brushes and commutators, to be replaced as in dc generators.
  • Quick response: The quick response saves the time and extends the life of the generator.
  • Response Time: Less than 3 seconds, when a resistance, the value of which corresponds to the central scale mark is suddenly inserted between measuring terminals
  • Limits Of Error: The insulation resistance measurement is accurate to within [+/-]5% of the indicated value over the effective range and within [+/-]10% of the indicated value at the scale mark for the rest of the ranges in conformity with I.S.2992-1980
  • Tolerance Of Voltage Across Measuring Terminals :Within [+/-]10% of the rated voltage for scale mark of infinity and more than 90% of the rated voltage for the central scale mark in confirmity with I.S.2992-1980.
  • Rotations Speed of Handling: 160 R.P.M.
  • Central Scale Mark: 1/50th of rated resistance value.
  • Insulation Resistance: More than 50 mega ohms between the electrical circuits and the case, when measured by applying 500V DC
  • Di-Electric Strength: Withstands 1 minute application of 2000 volts AC [rms] between the electrical circuits and the case
  • Weight: Approximately 3Kg. For model Y1-M1 and Y1-M2
  • Optional Accessories: 1 Carrying case 2. Test Leads.
  • Dimension: For Model Y1-M1 & Y1-M2: 170X100X110mm [approx].
